HENRY F. HAYDEN, OF \VASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO THE INTERNATIONAL VAPOR FUEL AND CARBON IRON AND MANU- FACTURING COMPANY, OF SAME PLACE.

APPARATUS FOR GENERATING VAPOR FROM LIQUID HYDROCARBONS.

. i SPECIFICATION formingpart of Letters Patent No. 278,79 3, dated June 5, 1883.

Application filed June 11,1881. Renewed March 26, 1883. (N0 model.) I I To all whom it may concern.-

Be it known that I, HENRY F. HAYDEN, a citizen of the United States of America, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Apparatus for Generating Vaporfrom Liquid Hydrocarbons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to that class of vaporgenerators in which steam is used for causing the vaporization of liquid hydrocarbons; and the nature thereof consists in certain improvements in the construction of the same, hereinafter shown and described.

It also consists in certain improvements in the construction of furnaces in which vapor fuel is burned.

In the accompanying drawings, Figure 1 is a vertical section of the apparatus. Fig. 2 illustrates in detail the arrangement of the superheating-pipes.

In the drawings, A designates the furnace, from whence the products of combustion pass upward to the smoke-pipe T.

B is the steam-superheater, which consists of a number of communicating coils of pipe arranged the one above the other. One of these coils is represented in plan in Fig. 2.

O is avalve for regulating the flow of superheated steam from the superheaterto the retort or generator G.

D is the oil-supply valve.

E is the pipe through which the superheated steam enters the generator.

F is the pipe through which the liquid hydrocarbon enters'the generator.

H is the pipe which conducts the vapor from the generator. I

I is a valve for regulating the flow of vapor to the point where it is consumed.

J is a receiver for residuum, provided with a valve, K, through which the residuum may be drawn oflr.

L is a tanklin which the hydrocarbon is held at a required pressure by means of a loaded valve, R.

N is a perforated platefor supplying air to the burner M.

O is the combustion-chamber.

P is the pump by which the liquid hydrocarbon is forced upward from the tank Q.

The operation of the apparatus is as follows: The superheater B and the generator or retort G are heated to the degree required for the vaporization of the liquid hydrocarbon by the heated gases which rise from the furnace A. Free steam is admitted to the superheater B, from whence it passes to the generator G, its flow being regulated by the valve 0. The liquid hydrocarbon is introduced into the said generator immediatelybelow the point at which the steam enters through the pipe F, and is vaporized by the action of the steam. The retort G is slightly inclined, so that if any of the heavier hydrocarbons are not vaporized they will flow into the receiver J, located at the side, of the casing of the apparatus, from whence they may be drawn off through the valve K. It will thus be seen that this arrangement of '7 5 the generator G and the receiver J will prevent the hydrocarbons which have not been vaporized from lodging in the retort Gor being carried away through the pipe H. It is also to be observed that the receiver J, being outside of the casing, is not subjected to the heat imparted by the escaping products of combustion. The flow of vapor to the burner H is regulated by the valve I. The burner M, which consists of a perforated pipe, is supplied with air heated to about 500 in its passage through the fiue, Y, arranged on top of the furnace X by means of the curvaluna perforated plate N. By this arrangement the heated air is thoroughly intermixed with the vapor entering through the perforations in the burner M and carried forward to the combustion-chamber, which consists of a number of pillars, Z, of refractory mateiral, arranged within the mixing-chambers of the furnace. The burner and furnace in 5 which the gas is burned are not claimed in this application, as they will form the subject-matter of another application for Letters Patent of the United States. The tank L is supplied with liquid hydrocarbon by means of the pump I00 1?, connected with the reservoir Q, the pressure in the tank being regulated byvthe loaded valveR, which may be set at a pressure of twenty pounds to the square inch. The sur- 5 plus hydrocarbon is returned to the tank Q,

from whence it was taken by a pipe communicating therewith. The residuum removed from the receivers J through the valve K may be mixed with coal or'other fuel used in the 10 furnace.

It will thus be seen that by the apparatus the lighter hydrocarbons maybe continuously I liquid hydrocarbons, an inclined generator arranged above the superheating-pipes, and pro vide'd with a vertical receiverarranged on the outside of the casing of the apparatus.

2. The combination of the superheater B, the steam-supply pipe E, the inclined generator G, and the hydrocarbonsupply pipe F, as and for the purposes described.

3. The combination of the generator G, the hydrocarbon-supply pipe F, the tank L, pump P, and loaded valve R, as and for the purposes described.
